APPARATUS FOR MANUFACTURING ICE.

SPECIFIECATION forming pa-t of Letters Patent No. 672,036, dated April16, 1901. Application filed January 6, 1900. Serial he. 581. (No model.)

My invention has relation to apparatus for to producing ice in plate orblock form in a pure state and without air-needles and internalhoneycomb conditions.

The principal object of my invention is to provide an apparatus forproducing plate or I block ice solidly, cheaply, and expeditiously inapure condition without air-needles and internal honeycomb conditions.

My invention consists ofthe improvements in apparatus for themanufacture of ice, substantially as hereinafter described and claimed.

The nature and characteristic features of my present invention will bemore fully understood from the following description, taken inconnection with the accompanying drawing, illustrating, partly inelevation and partly in section,- an apparatus of my invention for thesnaking of pure ice.

Referringto the drawing of the plant as illustrated, A represents awater-heater, provided internally with a series of staggered ballleplates a, and above the same is a watersupply pipe a, with a transversedistributing branch at for discharging the water onto the respectiveseries of bafllcplates a of the heater. Beneath the baliieplates a ofthe heater A is disposed transversely thereof a perforated steampipe aleading from a source of steam-supply, (not-shown) and in the lowerportion of said heater is provided a reservoir 0;, having an outlet-pipec with a stop-cock a. This outlet-pipe leads into an open tank or vesselll,within which the heated water of the apparatus A is conveyed, so thatair and noxious gases carried therewith or contained in said water maybe liberated therefrom into the atmosphere. The open tank or vessel llis provided with an'outl -lcock I: for cleansing the same or removingsedimentation accumulating in the botiomot' the sanntherefrom. 'lhistank is also provided with an outlet-pipe 5, having a cock b and whichpipe leads to and is connected with a cooling-tank 0, within whichpreferably the said pipe is formed into a coil 0, and from which coilextends a pipe 0' intoa freezing or ice-forming tank or vessel D. v

c is a pipe connected with the upper portion of the cooling-tank C, inconnection with Y a suitable source for conveying cooled or cold watertherethrough into the said tank orvessel O, and thereby to reduce thetemperature of the water from the open tank Bin its passage through thecoils c of the tank 0 and pipe 0 into the freezing or ice-forming tankor vessel D. This pipe 0' is provided with a stopcock 0 and is connectedby a T-shaped union with a pump E and from which pump a pipe e extendsto the lower portion of the freezing or ice-forming tank or vessel D andis connected therewith by means of a series of branch pipes 01, eachprovided with a stop cock d. The freezing or ice-forming tank or vesselD is provided with a series of oblong cells (P, adapted to containbrine, ammonia, or other freezing media, which is introduced into saidcells through the series of pipes ('1 d represents the blocks of iceformed in said freezing or ice-forming tank or vessel D between thebrine-cells from each side thereof toward a median plane of the body ofWater contained between said cells, which water is frozen progressivelyin the direction of a median plane of the body of water containedtherein.

(1 represents the volume or body of water remaining after'the formationof the ice between the ammonia or brine cells (I and which water at alowered temperature may be utilized by being conducted through thebranch pipes d by opening the stop-cocks d thereof into the pipe (2 andby means of the pump E may be forced by cutting off the snppl of waterthrough the branch c" of the pi e c from the reggilar cooling source(not shown) 5 into the cooling-tank C for lowering the temperature ofthe water therein and priorto its discharge into the free ingorico-forming tank or vessel I). This, it will be understood, ofcourse, will be possible after the first formutor tion of the water intoblocks or plates of ice of the character illustrated for theexemplification of the invention in the freezing or. ice-forming tank orvessel D, thereby conserving the cooling of water from the main supplyand utilizing what is regarded in such icemaking as a waste water to agreater or less extent for the cooling of the subsequent-lytreated waterfrom the tank ii in its passage through the tank 0, and thus bringingthe same into a condition whereby expeditious freezing takes place afterthe temperature of the water has been reduced by passage through thecooling-tank G into the freezing or ice-forming tank or vessel D forassuming in due course blocks or plates of ice progressively produced inthe direction of a median plane of the body of water from the brine orammonia cells (1 of the freezing or ice-forming tank or vessel D. In thecooling-tank is provided an outlet-pipe 0 which may be connected withany suitable waste-receptacle. After the freezing or ice-forming tank Dhas received its full quota of water to become ice in the form,' forexample, as illustrated the stop-cock b of the pipe 7) is turned so asto cut olf the supply ofwater from the tank B through the cooling-tankC, and hence the supply of water contained in the freezing orice-forming tank or vessel D during freezing of the same progressivelyinto blocks or plates of ice remains in substantially a quiescent state,which is desirable for assuring blocks or plates of icewithoutboney-combed conditions and without internal air-needles. In themain such conditions are obviated according to my invention of producingice by the treatment of the water in the manner hereinbefore explainedof heating the same prior to its introduction into the open tank,because through the delivery of the water into and its rising in saidopen tank B air and noxious gases will be readily liberated therefromand anterior to the reduction of the temperature of the Water withoutcoming into contact with the atmosphere and prior to its assuming a moreor less quiescent state in the freezing or ice-forming tank or vessel Dto become plates or blocks of ice.

Having thus described the nature and object of my invention,what I claimas new, and desire to secure by Letters Patent, is-

1. An apparatus for manufacturing ice, comprising a heater provided withstaggered baffle-plates, a water-supply above the same, a steam-supplybeneath said plates, an open tank connected with said heater and adaptedto receive the heated water from said heater to permit of the liberationof air and gases from the water, a cooling-tank connected with said opentank, means for reducing the temperature of the water in its transitthrough said tank, without the reduced water coming into contact withthe atmosphere and an iceforming tank or vessel provided with a seriesof cells for containing brine, ammonia or other freezing media,substantially as and for the purposes described.

2. An apparatus for manufacturing ice, comprising a heater provided withstaggered bathe-plates, a water-supply above the same, a steam-supplybeneath said plates, an open tank connected with said heater and adaptedto receive the heated water from said heater to permit of the liberationof air and gases from the wn tor, a cooling-tank connected with saidopen tank, means for reducing the temperature of the water in itstransit through said tank, without the reduced water coming into contactwith the atmosphere, an ice-forming tank jor vessel provided with aseries of cells for containing brine, ammonia or other freezing media,and means connected with a .pump for-removing surpluslowered-temperature water therefrom and utilizing the same in saidcooling-tank, substantially as and for the purposes described.

3. An apparatus for manufacturing ice, comprising a heater connectedwith an open tank and the latter connected with a coolingtank havingtherein a coiled pipe and a pipe connction with a freezing orice-forming tank or vessel having a series of cells for containingbrine, ammonia or other freezing media, branch pipes from the bottom ofsaid tank or vessel connected with a pipe and the latter with a pump,and a pipe from a source of supply provided with a cock and alsoconnected with said pump-pipe, whereby surplus lowered-temperature waterfrom said freezing or ice-forming tank or vessel may be utilized forreducing the temperature of the water in its passage through saidcooling-tank, substantially as and for the purposes described.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
